TRIBOLOGICAL PROPERTIES OF Al/SiO2, NANOCOMPOSITE SHEETS PRODUCED BY ACCUMULATIVE ROLL BONDING (ARB) PROCESS

Accumulative roll-bonding process (ARB) is a well-known severe plastic deformation technique for production of the ultrafine grained, nanostructured and nanocomposite materials in the form of sheets. In the present study, this process used for manufacturing Al/SiO2 nanocomposites by using Aluminum 1050 alloy sheets and nano sized SiO, particles, at ambient temperature. After 8 cycles of ARB process, the mechanical properties, tribological properties and wear resistance of produced nanocomposites were investigated. The wear tests by abrasion were performed in a pin-on-disc tribometer. Results show that by increasing ARB cycles and the amount of nano powders, the friction coefficient decreases,
